Thought that I would post up my findings on what mag's work and what give me difficulties with the SU22 platform.
First off the SU22 is now over 2,000 rounds and all I did was to take it out of the box and shoot it. No lube, no cleaning anything and no malfunctions yet to report. Now that is out of the way lets talk about magazines for this rifle.
First up is the stock mag that comes with the rifle. You have to press in the mag release button when inserting the magazine on my rifle. Any one else experiance this issue with there's? Also you can modify it to hold 15 instead of 10 by removing the tabs inside the mag has been reported on other places but I have yet to try this. Has anyone out there attempted this? Further more I have been noticeing maring on the feed lips were the bolt rest's against. Any one else notice that the bolt hold open function doesn't work on it either?
Next up is the black dog 30 rounders with the metal feed lips. No maring and the ocasional FtF senario. Plus I do not have to press in the magazine button to seat the magazine and when I press the button to strip it out off the magwell. All I have to do is lock back the bolt carrier and depress the magazine release button and it falls right out of the rifle. To me it seems a little out of spec on the width for this rifle platform compared to the other magazines. Here are some picture's:
Then the last one I have tried is the black dog 50 round drum mag. Got to say it works just like the stock mag except it holds 40 more rounds. Plus I find it a little cumbersome when tring to activate my light switch button, not the pad. Shown here:
Tell me what you guy's think please and as for mounting rails to the handguard set I find that the magpul one's work good. If you need any just hit me up via pm.
